Dialogues Concerning Natural Religion

After I joined the company, whom I found sitting in Cleanthes 's library, Demea paid Cleanthes some compliments on the great care which he took of my education, and on his unwearied perseverance and constancy in all his friendships. The father of Pamphilus, said he, was your intimate friend: The son is your pupil; and may indeed be regarded as your adopted son, were we to judge by the pains which you bestow in conveying to him every useful branch of literature and science. You are no more wanting, I am persuaded, in prudence, than in industry. I shall, therefore, communicate to you a maxim, which I have observed with regard to my own children, that I may learn how far it agrees with your practice. The method I follow in their education is founded on the saying of an ancient, "That students of philosophy ought first to learn logics, then ethics, next physics, last of all the nature of the gods." This science of natural theology, according to him, being the most profound and abstruse of any, required the maturest judgement in its students; and none but a mind enriched with all the other sciences, can safely be entrusted with it.
